Featuring a lightweight contest between Jorge Gurgel and Joe Duarte, Strikeforce Challengers 18 takes place Aug. 12 at The Pearl at the Palms Casino Resort in Las Vegas.

It’s not clear if Green vs. Vieira will be part of the Showtime-televised main card.

Green, a three-and-a-half-year pro, has spent much of his career with KOTC, though he’s also made appearances with Affliction and Tachi Palace Fights. The 24-year-old, who trains with Pinnacle Jiu jitsu and MMA in California, owns seven knockouts and six submissions in 15 career victories.

Vieira joins the organization with four victories in his past five fights and six wins in his past eight bouts. The Brazilian jiu-jitsu black belt (under Murilo Bustamente), who’s put on many entertaining bouts in his native Brazil, has earned submissions in eight of his 12 career victories.

A total of 26 fighters got their chance to shine on Saturday as part of UFC 190 at Rio de Janeiro’s HSBC Arena. Now that UFC 190 is in the books, it’s time to commence MMAjunkie’s “Three Stars” ceremony.

The man known for cranking submissions to the point of injury added eye-gouging to his repertoire. But is the controversy of Rousimar Palhares too essential to his bizarre, awful appeal for his employers to take any meaningful action against him?
